Q. Look at this set of ordered pairs:\newline(8,16)(8, 16)\newline(5,4)(5, 4)\newline(6,20)(6, 20)\newlineIs this relation a function?\newlineChoices:\newline(A) yes\newline(B) no
  1. Understand the problem: Step 11: Understand the problem.\newlineWe need to check if the set of ordered pairs is a function. A relation is a function if each input (first number in each pair) has exactly one output (second number in each pair).
  2. List inputs and outputs: Step 22: List all the inputs and their corresponding outputs.\newlineInputs and Outputs:\newline- 88 maps to 1616\newline- 55 maps to 44\newline- 66 maps to 2020\newlineCheck if any input is repeated with different outputs.
  3. Check for repeated inputs: Step 33: Check for repeated inputs.\newlineFrom the list:\newline- 88 appears once\newline- 55 appears once\newline- 66 appears once\newlineSince no input is repeated with a different output, this relation is a function.
